Product details

The Siemens 5SU9346-1CN32 is a SENTRON RCBO — an RCD-operated circuit breaker combining overcurrent and residual current protection in a single 4-pole unit. Rated 32 A at AC with a 30 mA residual trip and C-curve characteristic, it handles mixed lighting and small motor loads on a 50/60 Hz supply.

The 32 A rating is the continuous current at 30 °C; at 40 °C it derates to 29.8 A, at 45 °C to 28.5 A, and at 50 °C to 27.8 A — so a panel running warm needs a headroom check. The 30 mA residual trip is the standard for personnel protection (shock hazard) per IEC 60364.

Panel integration

Installation depth is 70 mm. Touch protection is built in.

Frequently asked questions

What is the closest functional second-source for 5SU9346-1CN32?

The 5SU9304-1KK32 is the nearest parametric peer — same 4-pole, 30 mA residual, C-curve — but it's rated 25 A, not 32 A. It won't drop into a 32 A BOM line without verifying the load current fits the lower rating.

Where can I buy 5SU9346-1CN32 and get current pricing?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What are the key dimensions of 5SU9346-1CN32?

Width 126 mm (7 modular units), depth 77 mm, height 90 mm. Installation depth is 70 mm.

Will 5SU9346-1CN32 fit in a panel designed for 5SU9304-1KK32?

Both are 4-pole, 7-module-width RCBOs with the same DIN-rail footprint and top/bottom feed, so the mechanical fit is identical. The difference is the current rating — 32 A vs 25 A — which matters for the circuit, not the panel cutout.
